The rears will, yes. They will add about 3.5" of droop... works good with FJ80 front springs on the back of the 4runner. It's about the limits the rear suspension can handle. Compression then becomes a problem, unless you extend the bumpstops an inch or two. I have seen this done.
As for the struts on the front, I have not seen this done, but I am almost sure they would be too tall and over extend (lift) the front suspension.
